Paper Abstract

The guided wave acousto-optic Bragg interaction has been investigated in proton exchanged waveguides on X and Y-cut lithium niobate. 220 MHz Z-propagating surface acoustic waves were used to probe the piezoelectric, electro-optic, and acousto-optic properties of the proton exchanged waveguides. We have found that the electromechanical coupling coefficient is reduced significantly in these structures, as is the overall acousto-optic interaction efficiency. The reduced interaction efficiency is attributed to the lack of an electro-optic contribution resulting primarily from a reduced magnitude of the r33 electro-optic constant. We have also seen a very marked increase and strong temperature dependence in the surface acoustic wave attenuation.
